[Abstract]:In desulphurization gypsum resource treatment process, steam rotary drying process is recognized by gypsum industry for its advantages.Because the heat transfer of steam rotary dryer is very complex, there is no design criterion at home and abroad, and the related research results are scarce.It is very valuable to study the heat transfer mechanism of steam rotary dryer by means of theoretical analysis and experimental study.The mechanism of steam rotary drying of desulphurized gypsum, the effect of heat transfer process of heat transfer tube and the heat transfer parameters of dryer on the heat transfer effect are analyzed.This paper introduces the main characteristic parameters of dryer, the general calculation method of heat transfer coefficient of heat transfer pipe and the problems existing in the method.In order to analyze the influence of main technological parameters on drying heat transfer of desulphurized gypsum steam rotary dryer, a steam rotary experimental system was designed, the experimental principle and flow were discussed, and the experimental equipment and instrument were calibrated.In order to obtain the measurement data accurately, the experimental parameters of the desulfurized gypsum steam rotary test bench were set up, and the rotational speed of the experiment was determined by analyzing the six states of the gypsum powder particles in the dryer. At the same time, the experiment was designed to measure the heat loss of the test bench.Cold state experiment step and hot state drying experiment step.A total of 54 groups of experiments were carried out in cold and hot state by means of desulphurization gypsum steam rotary test bench.In order to analyze the effects of cylinder speed, material filling rate, heat transfer pipe position, fin of heat transfer pipe on average heat transfer coefficient and heat transfer pipe time of desulphurized gypsum steam rotary drying system, the data obtained are classified and analyzed.The influence curves of various factors on heat transfer are obtained.
